Rotating device id representation in TLV Additional Data needs to be …

…aligned with the spec (project-chip#9455) * RotatingId: version0 * RotatingId: version1 * RotatingId: version0 * RotatingId: version1 * Fix Darwin host build (project-chip#3990) #### Problem Some conversions to use PacketBufferHandle (project-chip#3909) broke Darwin builds, which aren't currently run in CI. #### Summary of Changes Fix src/platform/Darwin/BleConnectionDelegateImpl.mm to match the API change in project-chip#3909. * Add '-Wextra' to compiler flags (project-chip#3902) * Implement Level Control Cluster (project-chip#3806) * New seekbar in Android CHIPTool * Sample usage in lighting-app/nrfconnect Signed-off-by: Markus Becker <[email protected]> * Fix Rendezvous over BLE after recent changes (project-chip#4012) PR project-chip#3704 introduced a change that the BLE transport in RendezvousSession is only initialized when PeerAddress in RendezvousParams is of type BLE. However, PeerAddress isn't initialized anywhere. As a result Rendezvous over BLE stopped working between Android CHIPTool and accessories. Btw, remove an assert related to the storage delegate as it seems an optional member of the device controller. * [thread] fix invalid configuration of active dataset (project-chip#4008) * Fix data loss or crash in TCPEndPoint with LwIP (project-chip#4022) * Fix data loss or crash in TCPEndPoint with LwIP #### Problem Under the configuration CHIP_SYSTEM_CONFIG_USE_LWIP, in some cases where the data size exceeds the TCP window size, TCPEndPoint can either die or lose data when accounting of un-acked data falls out of sync. #### Summary of Changes Imported fix from Weave: * This change removes separate accounting of the unsent data position and replaces it with simple counting of sent-but-not-acked data and a skip-loop at the start of DriveSending(). Fixes project-chip#4013 - Data loss or crash in TCPEndPoint with LwIP * Restyled by clang-format Co-authored-by: Restyled.io <[email protected]> * Update lighting-app gen/ folder with ZAP generated content (project-chip#4010) * Fix segmentation fault error in response echo message (project-chip#3984) * Add back Android default build coverage & fix the build (project-chip#3966) mDNS doesn't build with no device layer. Remove it from the build and add back the coverage that would catch this that was lost in project-chip#3340. * Update all-clusters-app gen/ folder with ZAP generated content (project-chip#3963) * Move src/inet/tests to auto-test-driver generation (project-chip#3997) * Rename TestUtils to UnitTestRegistration. (project-chip#4021) Looking to remove usage of 'Utils' unless we have really no choice. 'UnitTestRegistration' seems clearer in what it does compared to 'TestUtils'. * Update src/lib/core/tests to auto-test-driver generation (project-chip#3991) * Cleanup zap chip-helper.js (project-chip#3973) * Cleanup zap chip-helper.js * Restyled by clang-format Co-authored-by: Restyled.io <[email protected]> * Move src/transport/tests to auto-test-driver generation (project-chip#3999) * Move src/transport/tests to auto-test-driver generation * Add relevant libraries (and more test-capable libs) to nrf. * Refactor inet test helpers (to not include actual inet tests), try to make qemu allow better linkage but still failed for transport tests so disabled for now * Added more tests on esp32 qemu * Restyle fixes * Fix cast errors in InetCommon * Disable raw tests from zephyr: somehow they fail running out of endpoints * Disable DNS test on zephyr * Remove inet endpoint test from zephyr * Remove inet endpoint test from zephyr - fix again * Modify gitignore * Restyle fixes * Use CHIPDeviceController instead of CHIPDeviceController_deprecated (project-chip#3979) * Implement the missing part of Exchange Header in Transport layer (project-chip#4017) * Implement the missing part of Exchange Header in Transport layer * Revert comment 'if' back to 'iff'("if and only if") * Remove duplicated send flag defines and put ExchangeMgr/ExchangeConte… (project-chip#3994) * Remove duplicated send flag defines and put ExchangeMgr/ExchangeContext under the same namespace as CRMP * Rename kSendFlag_Default to kSendFlag_None * Move src/lib/asn1/tests and src/ble/tests to auto-test-driver generation (project-chip#3998) * Move src/lib/asn1/tests and src/ble/tests to auto-test-driver generation * Remove one more unused file * Attempt to enable asn1 and ble tests in esp32 - see if they pass or not * Fix merge error * Update include header for ASN1 test * Include ASN1 in libCHIP * Some conversions to use PacketBufferHandle (project-chip#4011) * Some conversions to use PacketBufferHandle #### Problem Code should use `PacketBufferHandle` rather than `PacketBuffer *`. #### Summary of Changes - Converts remaining receive path in //src/inet and //src/transport. - Converts most of //src/ble. - Introduces Handle versions of the `AddToEnd`/`DetachTail` pair. Part of issue project-chip#2707 - Figure out a way to express PacketBuffer ownership in the type system * Restyled by clang-format * review * revive BtpEngine::Clear[TR]xPacket() * simplify conditional * (void) message.DetachTail() → message.FreeHead() * remove ExchangeContext::kSendFlag_RetainBuffer * missed pBuf.IsNull() * DetachHead() → PopTail() * typos Co-authored-by: Restyled.io <[email protected]> * Move src/system/tests to auto-test-driver generation (project-chip#4000) * Move src/system/tests to auto-test-driver generation * Remove a TCP/IP init call that was killing qemu * Remove explicit "all" target from root build file (project-chip#3967) The "all" target exists implicitly and contains everything. We don't need to specify one, and it's misleading to do so specifying deps has no effect. * Make src/setup_payload compile with -Werror=conversion (project-chip#4032) * Add SSID and password to chip-tool pairing (project-chip#4054) * Get temperature-measurement and all-clusters-app to use examples/common/chip-app-server (project-chip#4039) #### Problem PR project-chip#3704 introduced a change where a `PeerAddress` is now required in order to start `RendezvousSession`. Sadly the multiple code paths bootstrapping `RendezvousSession` has not been updated. PR project-chip#4012 add a fix for some of the `examples/` but not for the `all-clusters-app` nor the `temperature-measurement-app`. To avoid such situation, this PR merge `examples/common/chip-app-server` and the custom code from `all-clusters-app` and `temperature-measurement-app`. One of the more discutable change of this PR (imo) is the code that moves the custom `Echo` mechanism from the `all-clusters-app` to `chip-app-server`. I was hoping to get rid of it before doing this change but the `all-clusters-app` and the `temperature-measurement-app` are broken since project-chip#3704 and this PR should fix that. Also I have a PR (mostly) ready once project-chip#3979 lands to get rid of this `Echo` specific code and replace it by a manufacturer specific `ping` command. #### Summary of Changes * Remove `EchoServer.cpp`, `RendezvousDeviceDelegate.cpp` and `include/RendezvousDeviceDelegate.h` from `all-clusters-app` * Remove `ResponseServer.cpp`, `RendezvousDeviceDelegate.cpp` and `include/RendezvousDeviceDelegate.h` from `temperature-measurement-app` * Introduce `chip-app-server/include/AppDelegate.h` in order to keep the behavior the `all-clusters-app` that turns on/off leds on different events. Maybe it should be converted to some types of `ChipDeviceEvent` or `CHIPCallback` at some point. * Fix `chip-app-server` to accomodate for the specifics of `all-clusters-app` * Add all Thread ULA addresses to the lwip interface (project-chip#4053) ULA prefixes will used for CHIP network so we need to add all these addresses to the interface. * Remove src/lib/message. (project-chip#4055) * Remove src/lib/message. Updated messaging implementation lives in src/messaging and the src/lib/message is not currently compiled or linked in. This saves us from looking at this code when some refactoring is needed (e.g. the SystemPacketBuffer changes). * Remove one more unused file * [ChipTool] Add Payload Parse Command (project-chip#3696) * [ChipTool] Add Payload Parse Command * [ChipTool] Add Payload Parse Command * [ChipTool] Restyle issues resolved * Restyled by whitespace * Resolve build errors caused by Command.h schema change Co-authored-by: lijayaku <[email protected]> Co-authored-by: Restyled.io <[email protected]> * rename ParseCommand to QRCodeParseCommand * adding AdditionalDataParseCommand version 0 * Adding parsing logic + logging * adding another parsing method * Basic Parsing is DONE * fixing memory issue * removing some logs * removing more logs * minor update * Add RotatingDeviceId to DNS-SD * Revert "Merge pull request #4 from hnnajh/rotating-id-test" This reverts commit 0235d05, reversing changes made to 3e1a4b9. * Storing RI in Octet String + Adding Binary format for BLE * Fixing rotating id parser + adding unittests * restyling * refactoring rotating id unit tests * Added more unit tests for Rotating Device Id * updated styling * refactor RI tests * Added RI Unittest + more validation * applying restyling * Fix CI * update styling * Fix CI * Update Styling * Fix CI * Restyling * Fixing nits * Using MutableByteSpan in RI generation * Fixing nits Co-authored-by: Kevin Schoedel <[email protected]> Co-authored-by: Vivien Nicolas <[email protected]> Co-authored-by: Markus Becker <[email protected]> Co-authored-by: Damian Królik <[email protected]> Co-authored-by: Łukasz Duda <[email protected]> Co-authored-by: Restyled.io <[email protected]> Co-authored-by: Yufeng Wang <[email protected]> Co-authored-by: Michael Spang <[email protected]> Co-authored-by: Andrei Litvin <[email protected]> Co-authored-by: jepenven-silabs <[email protected]> Co-authored-by: Boris Zbarsky <[email protected]> Co-authored-by: Jiacheng Guo <[email protected]> Co-authored-by: Liju Jayakumar <[email protected]> Co-authored-by: lijayaku <[email protected]>
